GraphExeter is a flexible, transparent and highly conductive thin film material with extraordinary mechanical, optical and electrical properties. The material is manufactured by intercalating Few Layer Graphene (FLG) with Ferric Chloride molecules. It tolerates 100% humidity and operates at temperatures >600 deg C. Industrial scale manufacturing could overcome the environmental impact and cost of alternative materials.
Exeter scientists have developed a scaleable process to manufacture Graphene inks and a novel technique for depositing Graphene on pre-patterned flexible substrates using an IPA-assisted method. The technology can be used to screen print circuitry at a very high resolution with track widths <10 microns. The technology could be a cost effective alternative to the high volume manufacture of flexible electronic devices.
Graphcrete is a liquid exfoliated Graphene concentrate, which when added to concrete doubles its strength and reduces its permeability to water ingress. The impact of Graphene concentrates in other composite materials is also being explored and with a readily scaleable manufacturing process this technology has the potential to fundamentally reduce the cost and environmental impact of construction.
